Abstract

Die Erfindung betrifft ein Mittel zur Abdeckung von UV-emittierenden Strahlungsquellen auf der Basis von Acrylglas, wobei das Acrylglas einen Gehalt an Farbmitteln innerhalb eines Konzentrationsbereichs von 0,0005-0,3 Gew.-% (berechnet auf eine Schichtdicke der elektroma­ gnetische Strahlung absorbierenden Matrix von 1 mm), die im sichtbaren Bereich des Spektrums zwischen 400 und 550 nm absorbieren und bei einer in diesem Bereich liegenden Wellenlänge eine Absorption von mindestens 2% besitzen und die gleichzeitig im A- und im B-Bereich der UV-Strahlung einen spektralen Transmissionsgrad T(λ) von im Mittel nicht unter 55% und bei keiner Wellen­ länge in diesem Bereich von weniger als 10% besitzen. The invention relates to a means for covering UV-emitting radiation sources based on acrylic glass, the acrylic glass containing colorants within a concentration range of 0.0005-0.3 wt .-% (calculated on a layer thickness of the electromagnetic radiation absorbing Matrix of 1 mm) which absorb in the visible range of the spectrum between 400 and 550 nm and which have an absorption of at least 2% at a wavelength in this range and which simultaneously have a spectral range in the A and B range of UV radiation Transmittance T (λ) of on average not less than 55% and at no wavelength in this range of less than 10%.
